Owners of CCR facilities with impacted groundwater require consultants with reliable experience in monitoring, assessment, and remediation services to comply with regulations. Geosyntec has demonstrated experience in groundwater characterization and development of robust conceptual site models (CSMs) which serve as the foundation for understanding migration pathways, exposure risks, and remedial alternative evaluations.
In addition to monitoring, assessment, and remediation, Geosyntec's services also include feasibility and technology evaluation for groundwater remedial action selection and design. We can design, implement, and optimize traditional treatment technologies (e.g., pump and treat), but when site conditions allow, we are also adept at developing and implementing advanced technologies such as redox controls and the TreeWell® technology for in situ remediation of inorganics like arsenic and selenium. Other groundwater approaches and considerations including the following:
- We have gained regulatory approval of natural attenuation remedies and technically justified alternative source demonstrations, potentially saving millions of dollars in unnecessary treatment costs.
- Our geochemistry modeling expertise can be critical to understanding changing subsurface conditions and potential mobilization of naturally occurring metals in groundwater during CCR facility excavation and/or construction.
Geosyntec continues to advance the practice through technical innovations and partnerships. For example, in collaboration with the Electric Power Research Institute (EPRI) and a utility client, we are evaluating the use of biogeochemical processes for CCR immobilization, including the ability to analyze key DNA targets to monitor the process. In addition, EPRI and the Interstate Technology & Regulatory Council (ITRC) frequently request Geosyntec to author key guidance documents (e.g., on monitored natural attenuation [MNA] of groundwater), remedial technology fact sheets, and other related topics.
